Thanks to all with comments so far. I spent all of yesterday under the car. First I thought I would try some diagnosis by removing the pan. Fluid looks fine and there was enough of it as well. The magnet had some fuzz on it but nothing out of the ordinary. I then dug into the valve body, eventually removing the whole thing and dismantling it. I found quite a few passages that were blocked with black sludge and even a little bit of white sludge (water in oil type of white sludge). The black and white sludge wasn't too bad but I don't reckon it would be too good inside the tranny. About a year ago we had to replace the radiator due to a leak in the tranny oil cooler. Perhaps this is where the water got into the system. I could see where a transmission flush would have done this car a lot of good. Too bad I didn't do it last year. I just recently started reading this site in earnest. Anyway, I decided to drop the tranny because I didn't find a smoking gun. I was going to buy some gaskets (and a manual too) and reassemble the valve body ( including all those little balls that went flying everywhere) but what if the pump or something else was bad as well? My friend suggested that perhaps the tranny pump went due to a loss of a seal - anybody have experience with this? I am thinking that deep inside the tranny there is some of that white or black sludge clogging one of the valves or pistons. I also found the output bushing was completely bagged out on the tranny. so that would have necessitated removing half of the tranny anyway. So now the tranny is sitting on a bench, and I am looking for a used one in the NYC area. Any suggestions? BTW, this is a 1990 DL 245 with the notch for the crank sensor and it has not speedo cable hook-up suggesting perhaps a aw-71. I thought that it would have been an aw-70. The tag says 03-70 and some other numbers I can't remember right now. Thanks in advance to any replies. Erik
